America is a country created by white people with white culture, white religion, white values and ethics and was previously 85% white
By 2045 America will be less than 50% white and by 2065 will be less than 40% white etc etc. Without white people America will dissolve and split up into a dozen new countries based on religious/ethnic/political identities. They will always be at war with each other because america core culture has always been selfishness, war and division.
North Korea will be around for far longer than America and thats 99% definitive
